Olli's place is very well located (a few minutes' walk through a charming street lined with market vendors during the weekday, to the nearest BTS, Chong Nonsi) and is a good value. There is a 7-11 right across, and Silom Road is literally right there, down the street. BTS Sala Daeng and MRT Silom is also within walking distance. Many shops and great Bangkok atmosphere nearby, including one of its famed night markets. Great for tourism!
